...and it appears that your question is still unaddressed.
Your map will publish with vehicles, weapons, and AI in them. They just won't be there when you play an online game.
The only map I published has all three in it, but not when played online. Just in the editor.
Hopefully they will have an update that allows us to make and play story mode maps online. They would need to increase the number of AI we're allowed to place though.
